-Required properties:
-- compatible: Must be one of the following:
-	- "microchip,mcp3021" for mcp3021
-	- "microchip,mcp3221" for mcp3221
-- reg: I2C address
-
-Optional properties:
-
-- reference-voltage-microvolt
-	Reference voltage in microvolt (uV)

-	reg = <0x4d>;
-
-	reference-voltage-microvolt = <4500000>; /* 4.5 V */
